DETAILED DESCRIPTION

In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented herein. It will be readily understood that the aspects of the present disclosure, as generally described herein, and illustrated in the Figures, can be arranged, substituted, combined, separated, and designed in a wide variety of different configurations, all of which are explicitly contemplated herein.

This disclosure is generally drawn, inter alia, to methods, apparatuses, systems, devices, and computer program products related to schemes for providing a wireless local area network. Technologies are generally described for configuring an ad-hoc network group and providing a wireless local area network to at least one end device which is included in the configured ad-hoc network group.

In some examples, an end device may connect to an access point that provides a wireless local area network and then, the end device may serve as a provisional access point in relations with other end devices. In such a case, the end device may be called as a “master device.” The end device may invite at least one other end device to connect to the end device and configure a provisional network group including the at least one other end device that connects to the end device. The end device may calculate a network load of the end device, a network load of each of the at least one other end device, and a sum of the network load of the end device and the network load of the at least one other end device. Then, the end device may configure an ad-hoc network group based on the calculated network load of the end device, the calculated network load of the at least one other end device, and the sum of the network load of the end device and the network load of the at least one other end device. For example, the end device may compare the calculated network load of the end device and the calculated network load of each of the at least one other end device. As a result of the comparison, if the difference between the calculated network load of the end device and the calculated network load of each of the at least one other end device is larger than a predetermined value, the end device may instruct one or more of the at least one other end device to leave the provisional network group. Thereafter, the ad-hoc network group may be configured, and the end device may act as an access point that provides a wireless local area network to the at least one other end device which is included in the ad-hoc network group.

FIG. 1A schematically shows an illustrative example of a network communications environment 100 including an access point 110, a first device 120, a second device 130 and a third device 140, arranged in accordance with at least some embodiments described herein. FIG. 1B schematically shows another illustrative example of a network communications environment 101 including access point 110, first device 120 and third device 140, arranged in accordance with at least some embodiments described herein. By way of example, but not limited to, first device 120, second device 130 and third device 140 may respectively include any type of a mobile device, a portable device or a personal communication terminal which is able to use and control a wireless network such as a Wi-Fi network. As illustrated in FIGS. 1A and 1B, first device 120 may connect to access point 110 and access point 110 may provide a wireless local area network to first device 120. Thus, first device 120 may be a master device that provides the wireless local area network to other devices. Access point 110 may include a Wi-Fi access point and the wireless local area network provided by access point 110 may include a Wi-Fi network.

In accordance with at least one example embodiment, first device 120 may transmit a request of connecting to first device 120 to second device 130. Further, second device 130 may transmit a request of connecting to second device 130 to third device 140. As a response to the request, second device 130 which wants to connect to first device 120 may transmit, to first device 120, a response of connecting to first device 120 and first device 120 may receive the response from second device 130. Further, third device 140 which wants to connect to second device 130 may transmit, to second device 130, a response of connecting to second device 130 and second device 130 may receive the response from third device 140.

Upon exchanging the requests and responses, a provisional ad-hoc network group may be configured. First device 120, second device 130 and third device 140 may be included in the provisional ad-hoc network group. First device 120, second device 130 and third device 140 which are included in the provisional ad-hoc network group may further exchange information regarding each device such as Internet Protocol (IP) address of each of first device 120, second device 130 and third device 140, a media access control (MAC) address of each of first device 120, second device 130 and third device 140 and so forth.

First device 120 may calculate a network load difference between each network load of first device 120, second device 130 and third device 140. For calculating the network load difference, first device 120 may calculate the network load of first device 120. In some embodiments, first device 120 may calculate the network load of first device 120 based at least in part on contents information regarding contents to which first device 120 accesses. By way of example, but not limitation, the contents information may include at least one of Uniform Resource Locator (URL) or Internet Protocol (IP) address of a website to which first device 120 accesses. First device 120 may derive at least one of characters, images or texts from the obtained contents information as keywords. Then, first device 120 may calculate the network load of first device 120 based on the keywords derived from the obtained contents information.

Further, second device 130 may obtain contents information regarding contents to which second device 130 accesses. By way of example, but not limitation, the contents information may include at least one of Uniform Resource Locator (URL) or Internet Protocol (IP) address of a website to which second device 130 accesses. Second device 130 may derive at least one of characters, images or texts from the obtained contents information as keywords. In some embodiments, second device 130 may transmit the keywords derived from the obtained contents information to first device 120. Upon receiving the keywords derived from the obtained contents information from second device 130, first device 120 may calculate the network load of second device 130 based on the received keywords.

Similarly, third device 140 may obtain contents information regarding contents to which third device 140 accesses and derive keywords from the contents information. Then, third device 140 may transmit the keywords to first device 120. Upon receiving the keywords derived from the obtained contents information from third device 140, first device 120 may calculate the network load of third device 140 based on the received keywords.

In some embodiments, second device 130 by itself may calculate the network load of second device 130 based on the keywords derived from the obtained contents information. Further, second device 130 may transmit the calculated network load of second device 130 to first device 120 and the calculated network load of second device 130 may be received by first device 120.

Further, third device 140 by itself may calculate the network load of third device 140 based on the keywords derived from the obtained contents information. Further, third device 140 may transmit the calculated network load of third device 140 to first device 120 and the calculated network load of third device 140 may be received by first device 120.

In some embodiments, first device 120 may calculate the network load difference between each network load of first device 120, second device 130 and third device 140. Further, first device 120 may determine whether the network load difference between the network load of first device 120 and the network load of second device 130 is larger than a predetermined value. Further, first device 120 may determine whether the network load difference between the network load of second device 130 and the network load of third device 140 is larger than the predetermined value.

Upon determining, if the network load difference between the network load of first device 120 and the network load of second device 130 is the same with or smaller than the predetermined value and the network load difference between the network load of second device 130 and the network load of third device 140 is the same with or smaller than the predetermined value, as illustrated in FIG. 1A, first device 120 may configure an ad-hoc network group 150 including first device 120, second device 130 and third device 140. Then, first device 120 may provide a wireless local area network to second device 130 and third device 140 included in ad-hoc network group 150. The wireless local area network provided by first device 120 may include a Wi-Fi network provided by access point 110.

First device 120, second device 130 and third device 140 which are included in ad-hoc network group 150 may exchange signals informing that first device 120, second device 130 and third device 140 are included in ad-hoc network group 150 with a certain intervals. In some embodiments, first device 120 may transmit a signal informing that first device 120 is included in ad-hoc network group 150 to second device 130 and receive a signal informing that second device 130 is included in ad-hoc network group 150 from second device 130. Further, second device 130 may transmit a signal informing that second device 130 is included in ad-hoc network group 150 to first device 120 and third device 140. Further second device 130 may receive a signal informing that third device 140 is included in ad-hoc network group 150 from third device 140 and the signal informing that first device 120 is included in ad-hoc network group 150 from first device 120. Further third device 140 may transmit the signal informing that third device 140 is included in ad-hoc network group 150 to second device 130 and receive the signal informing that second device 130 is included in ad-hoc network group 150 from second device 130.

Further, after configuring ad-hoc network group 150, first device 120 may check if the network load of second device 130 or third device 140 is changed to be considerably different from the network load of neighboring devices. By way of example, but not limited to, if the network load difference between the network load of first device 120 and the network load of third device 140 becomes larger than the predetermined value, first device 120 may instruct third device 140 to leave ad-hoc network group 150.

In some embodiments, if the network load difference between the network load of first device 120 and the network load of second device 130 is larger than the predetermined value, first device 120 may instruct second device 130 to leave the provisional ad-hoc network group. For example, if a movie which requires a large amount of network load is played on first device 120 but an e-mail which relatively requires a small amount of network load is loaded on second device 130, the network load difference between the network load of first device 120 and the network load of second device 130 may be considerable. Then, first device 120 may instruct second device 130 on which the e-mail is loaded to leave the provisional ad-hoc network group.

Further, if the network load difference between the network load of second device 130 and the network load of third device 140 is larger than the predetermined value, first device 120 may instruct second device 130 or third device 140 to leave the provisional ad-hoc network group. For example, if an e-mail which relatively requires a small amount of network load is loaded on second device 130 while a game which requires a large amount of network load is played on third device 140, the network load difference between the network load of second device 130 and the network load of third device 140 may be considerable. Then, first device 120 may instruct second device 130 to leave the provisional ad-hoc network group. As a result, as illustrated in FIG. 1B, an ad-hoc network group 160 including first device 120 and third device 140, where the respective network loads are similar with each other, may be configured. Then, first device 120 may provide a wireless local area network to third device 140 included in ad-hoc network group 160.

Further, after configuring ad-hoc network group 160, first device 120 may check if the network load of third device 140 is changed to be considerably different from the network load of first device 120. If the network load of third device 140 becomes small, so that the network load difference between the network load of first device 120 and the network load of third device 140 becomes larger than the predetermined value, first device 120 may instruct third device 140 to leave ad-hoc network group 160.

FIG. 2 schematically shows yet another illustrative example of a network communications environment 200 including access point 110, first device 120, second device 130 and third device 140, arranged in accordance with at least some embodiments described herein. As illustrated in FIG. 2, first device 120 may connect to access point 110. In accordance with at least one example embodiment, first device 120 may transmit requests of connecting to first device 120 to second device 130 and third device 140. If second device 130 and third device 140 want to connect to first device 120, second device 130 and third device 140 may respectively transmit, to first device 120, a response of connecting to first device 120 and first device 120 may receive the responses from second device 130 and third device 140.

Upon exchanging the requests and responses, a provisional ad-hoc network group may be configured. First device 120, second device 130 and third device 140 may be included in the provisional ad-hoc network group.

First device 120 may configure an ad-hoc network group 170 that includes first device 120, second device 130 and third device 140 based on a network load of each of first device 120, second device 130 and third device 140. As described with reference to FIGS. 1A and 1B above, first device 120 may obtain the network load of each of first device 120, second device 130 and third device 140.

In some embodiments, first device 120 may calculate the network load difference between each network load of first device 120, second device 130 and third device 140. In such cases, first device 120 may determine whether the network load difference between the network load of first device 120 and the network load of second device 130 is smaller than a predetermined value. Further, first device 120 may determine whether the network load difference between the network load of first device 120 and the network load of third device 140 is smaller than the predetermined value.

Upon determining, if the network load difference between the network load of first device 120 and the network load of second device 130 is larger than the predetermined value and the network load difference between the network load of first device 120 and the network load of third device 140 is larger than the predetermined value, as illustrated in FIG. 2, first device 120 may configure an ad-hoc network group 170 including first device 120, second device 130 and third device 140. By way of example, but not limitation, if a movie which requires a large amount of network load is played on first device 120 but an e-mail which relatively requires a small amount of network load is loaded on second device 130, the network load difference between the network load of first device 120 and the network load of second device 130 may be larger than the predetermined value. Further, if a movie which requires a large amount of network load is played on first device 120 but a twitter which relatively requires a small amount of network load is played on third device 140, the network load difference between the network load of first device 120 and the network load of third device 140 may be larger than the predetermined value.

Consequently, first device 120 whose the network load is relatively large and second device 130 and third device 140 whose the network loads are much smaller that of first device 120 may be included in the same ad-hoc network group 170. Then, first device 120 may provide a wireless local area network to second device 130 and third device 140 included in ad-hoc network group 170. The wireless local area network provided by first device 120 may include a Wi-Fi network.

Alternatively, upon determining, if the network load difference between the network load of first device 120 and the network load of second device 130 is the same with or smaller than the predetermined value, first device 120 may instruct second device 130 to leave the provisional ad-hoc network group. By way of example, but not limitation, if a movie which requires a large amount of network load is played on first device 120 and a game which requires a large amount of network load is played on second device 130, the network load difference between the network load of first device 120 and the network load of second device 130 may be smaller than the predetermined value. Then, first device 120 may instruct second device 130 to leave the provisional ad-hoc network group. As a result, first device 120 may configure an ad-hoc network group including first device 120 and third device 140.

Further, after configuring ad-hoc network group 170, first device 120 may check if the network loads of second device 130 and third device 140 are changed so that the network load difference between the network load of first device 120 and the network load of second device 130 and the network load of first device 120 and the network load of third device 140 become smaller than the predetermined value. By way of example, but not limited to, if the network load of third device 140 becomes large, so that the network load difference between the network load of first device 120 and the network load of third device 140 becomes smaller than the predetermined value, first device 120 may instruct third device 140 to leave ad-hoc network group 170.

Further, in some embodiments, first device 120 may calculate a total network load of ad-hoc network group 170 periodically. The total network load of ad-hoc network group 170 may be calculated by aggregating the network load of each of first device 120, second device 130 and third device 140.

First device 120 may compare the calculated total network load of ad-hoc network group 170 with an available network load of access point 110 periodically. Upon comparing, if the total network load is larger than the available network load of access point 110, first device 120 may instruct second device 130 and/or third device 140 to leave ad-hoc network group 170. By way of example, but not limited to, if the network load of third device 140 is changed to be large since the twitter has terminated and a game is played on third device 140, the total network load of ad-hoc network group 170 may be increased consequently. Accordingly, the total network load may become larger than the available network load of access point 110. Then, first device 120 may instruct third device 140 to leave ad-hoc network group 170.

FIG. 9 is a block diagram illustrating an example computing device that may be utilized to provide a scheme for providing wireless local area networks, arranged in accordance with at least some embodiments described herein. In these examples, elements of computing device 900 may be arranged or configured for a device. In a very basic configuration 902, computing device 900 typically includes one or more processors 904 and a system memory 906. A memory bus 908 may be used for communicating between processor 904 and system memory 906.

Depending on the desired configuration, processor 904 may be of any type including but not limited to a microprocessor (μP), a microcontroller (μC), a digital signal processor (DSP), or any combination thereof.

The present disclosure is not to be limited in terms of the particular embodiments described in this application, which are intended as illustrations of various aspects. Many modifications and variations can be made without departing from its spirit and scope, as will be apparent to those skilled in the art. Functionally equivalent methods and apparatuses within the scope of the disclosure, in addition to those enumerated herein, will be apparent to those skilled in the art from the foregoing descriptions. Such modifications and variations are intended to fall within the scope of the appended claims. The present disclosure is to be limited only by the terms of the appended claims, along with the full scope of equivalents to which such claims are entitled. It is to be understood that this disclosure is not limited to particular methods, reagents, compounds, compositions or biological systems, which can, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to be limiting.

With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.

It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to embodiments containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”

In addition, where features or aspects of the disclosure are described in terms of Markush groups, those skilled in the art will recognize that the disclosure is also thereby described in terms of any individual member or subgroup of members of the Markush group.

As will be understood by one skilled in the art, for any and all purposes, such as in terms of providing a written description, all ranges disclosed herein also encompass any and all possible subranges and combinations of subranges thereof. Any listed range can be easily recognized as sufficiently describing and enabling the same range being broken down into at least equal halves, thirds, quarters, fifths, tenths, etc. As a non-limiting example, each range discussed herein can be readily broken down into a lower third, middle third and upper third, etc. As will also be understood by one skilled in the art all language such as “up to,” “at least,” and the like include the number recited and refer to ranges which can be subsequently broken down into subranges as discussed above. Finally, as will be understood by one skilled in the art, a range includes each individual member. Thus, for example, a group having 1-3 cells refers to groups having 1, 2, or 3 cells. Similarly, a group having 1-5 cells refers to groups having 1, 2, 3, 4, or 5 cells, and so forth.

From the foregoing, it will be appreciated that various embodiments of the present disclosure have been described herein for purposes of illustration, and that various modifications may be made without departing from the scope and spirit of the present disclosure. Accordingly, the various embodiments disclosed herein are not intended to be limiting, with the true scope and spirit being indicated by the following claims.
